From its origins in counting and measuring it has evolved in highly sophisticated and elegant ways to become the language now used to describe much of the modern world. Mathematics is also concerned with collecting, analysing, modelling and interpreting data in order to investigate and understand real-world phenomena and solve problems in context. Mathematics provides a framework for thinking and a means of communication that is powerful, logical, concise and precise. It impacts upon the daily life of people everywhere and helps them to understand the world in which they live and work. Mathematics Specialised is designed for students with a strong interest in mathematics, including those intending to study mathematics, statistics, all sciences and associated fields, economics or engineering at university. This course provides opportunities, beyond those presented in Mathematics Methods, TQA level 3, to develop rigorous mathematical arguments and proofs, and to use mathematical models more extensively. AIMS Mathematics Specialised aims to develop students’: understanding of concepts and techniques drawn from algebraic processes, functions and equation study, complex numbers, matrices, calculus and statistics ability to solve applied problems using concepts and techniques drawn from algebraic processes, functions and equation study, complex numbers, matrices, calculus and statistics capacity to choose and use technology appropriately reasoning in mathematical contexts and interpretation of mathematical information, including ascertaining the reasonableness of solutions to problems capacity to communicate in a concise and systematic manner using appropriate mathematical and statistical language. COURSE SIZE AND COMPLEXITY This course has a complexity level of TQA level 3. At TQA level 3, the student is expected to acquire a combination of theoretical and/or technical and factual knowledge and skills and use judgment when varying procedures to deal with unusual or unexpected aspects that may arise. Some skills in organising self and others are expected. TQA level 3 is a standard suitable to prepare students for further study at the tertiary level. VET competencies at this level are often those characteristic of an AQF Certificate III. This course has a size value of 15. ACCESS It is highly recommended that students attempting this course will have previously successfully completed, or are concurrently studying, Mathematics Methods, TQA level 3. PATHWAYS This course is designed for students with a strong interest in mathematics, including those intending to undertake tertiary studies involving mathematics, statistics, all sciences and associated fields, economics or engineering. Tasmanian Qualifications Authority Version 1 Period of Accreditation: 1/1/2014 – 31/12/2017 Date of Publishing: 8 April 2020 3 Mathematics Specialised TQA Level 3 RESOURCES Programs of study derived from this course need to embrace the range of technological developments that have occurred in relation to mathematics teaching and learning. Students should have access to graphics calculators, including algebra-capable (CAS) calculators, and become proficient in their use. Graphics calculators can be used in this course in the development of concepts and as a tool for solving problems as appropriate. Refer also to the current TQA Calculator Policy that applies to TQA level 3 courses, available at http://www.tqa.tas.gov.au/0021. The use of computers is recommended as an aid to students’ learning and mathematical development. A range of packages is appropriate and, in particular, spreadsheets should be used. LEARNING OUTCOMES On successful completion of this course, students will: be self-directing; be able to plan their study; persevere to complete tasks and meet deadlines demonstrate an understanding of finite and infinite sequences and series demonstrate an understanding of matrices and linear transformations use differential calculus and apply integral calculus to areas and volumes use techniques of integration and solve differential equations demonstrate an understanding of complex numbers choose and use technology appropriately and efficiently. COURSE DELIVERY This course has an academic mathematical focus. The course content is presented under topic headings. The topics may be addressed separately but much of the content is inter-related and a more integrated approach is recommended and encouraged. It is also recommended that, where possible, concepts be developed within a context of practical applications. Such an approach provides students with mathematical experiences that are much richer than a collection of skills. Students thereby have the opportunity to observe and make connections between related aspects of the course and the real world and to develop further some important abstract ideas. Through engaging in learning activities derived from this course students have the opportunity to: gain deeper insight into the structure of mathematics meet intellectually challenging situations develop desirable attitudes towards mathematics. ROLE OF TECHNOLOGY It is assumed that students will be taught Mathematics Specialised with an extensive range of technological applications and techniques. If appropriately used, these have the potential to enhance the teaching and learning of mathematics. However, students also need to continue to develop skills that do not depend on technology. The ability to be able to choose when or when not to use some form of technology and to be able to work flexibly with technology are important skills in this subject.

Each of these proficiencies is essential, and all are mutually reinforcing. They are still very much applicable and should be inherent in the study, and applications, of four (4) topics of mathematics: Sequences and series Complex numbers Matrices Calculus. Each topic is compulsory and their content relates to Criteria 4 – 8. Criteria 1 – 3 apply to all four topics of mathematics. SEQUENCES AND SERIES The intention of this section of the course is that students will gain experience with a range of sequences and series by learning about their properties, meet some of the important uses of them, begin to understand the ideas of convergence and divergence and develop some methods of proof.

Tasmanian Qualifications Authority Version 1 Period of Accreditation: 1/1/2014 – 31/12/2017 Date of Publishing: 8 April 2020 9 Mathematics Specialised TQA Level 3 ASSESSMENT Criterion-based assessment is a form of outcomes assessment that identifies the extent of student achievement at an appropriate end-point of study. Although assessment – as part of the learning program - is continuous, much of it is formative, and is done to help students identify what they need to do to attain the maximum benefit from their study of the course. Therefore, assessment for summative reporting to the Tasmanian Qualifications Authority should focus on what both teacher and student understand to reflect end-point achievement. The standard of achievement each student attains on each criterion is recorded as a rating ‘A’, ‘B’, or ‘C’, according to the outcomes specified in the standards section of the course. A ‘t’ notation must be used where a student demonstrates any achievement against a criterion less than the standard specified for the ‘C’ rating. A ‘z’ notation is to be used where a student provides no evidence of achievement at all. Providers offering this course must participate in quality assurance processes specified by the Tasmanian Qualifications Authority to ensure provider validity and comparability of standards across all awards. Further information on quality assurance processes, as well as on assessment, is available in the TQA Senior Secondary Handbook or on the website at http://www.tqa.tas.gov.au. Internal assessment of all criteria will be made by the provider. Providers will report the student’s rating for each criterion to the Tasmanian Qualifications Authority. The Tasmanian Qualifications Authority will supervise the external assessment of designated criteria (*). The ratings obtained from the external assessments will be used in addition to those provided from the provider to determine the final award. QUALITY ASSURANCE PROCESSES The following processes will be facilitated by the TQA to ensure there is: a match between the standards of achievement specified in the course and the skills and knowledge demonstrated by students community confidence in the integrity and meaning of the qualification. Process - the Authority gives course providers feedback about any systematic differences in the relationship of their internal and external assessments and, where appropriate, seeks further evidence through audit and requires corrective action in the future.
